I have a psp slim I modded (2 years ago maybe?). I recently dusted off the PSP after not using it at all for over a year. Everything still works fine and I was playing an iso this morning. Its running 5.00 M33-6 on it with a few iso rips and an NES emulator. This mod was done on a PC running XP and a pandora battery I bought a while back. Since then, I have moved away from that PC and now have a MacBook Pro. So my questions are these: 1) Can I or should I upgrade to a newer version of CFW using Mac O/S? 2) Can I load emulators using Mac O/S? 3) Can I load iso's using Mac O/S? Everything I've read points to not being able to use a mac to initially mod the psp (am I wrong?). Nonetheless, its already modded and I haven't found any posts related to using a mac once the psp is already running CFW. Again, I no longer have access to a PC, let alone one running XP, and don't know how to run XP on my Macbook. I just want to add that I am still a noob, and only successfully got to where I am with this psp because of all the helpful and detailed posts on these forums, so thanks in advance to anyone willing to help.
